Hi
Since the splitting IPv6/4 configuration the bind ipv6 only flag is missing.
Otherwise the jsoninfo plugin is trying to listen ipv4 and ipv6 tcp socket.
jsoninfo ipv6 and ipv4 cant run at the same time.

olsrd.@LoadPlugin[7].library=olsrd_jsoninfo.so.0.0
olsrd.@LoadPlugin[7].ignore=0
olsrd.@LoadPlugin[7].accept=0.0.0.0

olsrd6.@LoadPlugin[1].library=olsrd_jsoninfo.so.0.0
olsrd6.@LoadPlugin[1].ignore=0
olsrd6.@LoadPlugin[1].accept=::

This is a workaround with side effects

+sysctl -w net.ipv6.bindv6only=1 > /dev/null

Please don't do that. This will break software that follows POSIX and RFC 2553.

The official solution to your problem is either to ensure that the IPv4 socket is bound before the IPv6 one, or to have the IPv6 code call setsockopt(IPV6_V6ONLY) before binding.
